“Africa is in need of help. Let all come who feel the call for the mission,” says Sister Domingas, who is responsible for the Saint Isabel Work of Charity for Children (OCSI) in Luanda. The missionaries of the Fraternidade – International Humanitarian Missions (FIHM) had a close acquaintance with the work of helping orphans and needy children carried out by the OCSI. In the third and last video recorded by the Missionaries with Sister Domingas, she emphasizes the relevance of the work done by the volunteers during the humanitarian activities. More than 24 thousand children and adolescents have already been helped by the social work led by Sister Domingas for almost 20 years.
